Review on Meddom Windshield Snow Cover - 4 Layer Protection, Ice, Snow, and Frost Shield for Car Windshields - Sun Shade for Car Windshield - Universal Fit for Most Cars and SUVs by Dave Hersma

Works but not without flaws. First, there's nothing to indicate top and bottom except for the wings that go into the doors. They're a little hard to see when you put it on, and it's annoying to unroll it only to flip it over to get the right side. Second, the case cannot be put back in the bag. Not too much of a problem for me, but another annoyance. Third, the magnets at the top and bottom don't really do anything. When the wind picks up, it becomes difficult to keep straight against the windshield. Eventually, one of the side mirrors came loose while being removed one morning. I'm willing to dismiss this as user error, but it still looks like poor stitching.
